Re: Silly Question, but...and real journalism.
It's within the The Communications (Television Licensing) (Amendment) Regulations 2016, the original legislation is part of the Communications Act 2003, which this substitutes.
I only found it this morning after 8.30am on the website legislation.gov.uk, which makes sense as it was implemented from today 01/09/2016.
Modification of the Communications Act 2003
9.—(1) In section 368 of the Communications Act 2003 (meanings of “television receiver” and “use”), for subsection (3) substitute—
“(3) References in this Part to using a television receiver are references to using it for—
(a)receiving all or any part of any television programme, or
(b)receiving all or any part of a programme included in an on-demand programme service which is provided by the BBC,
and that reference to the provision of an on-demand programme service by the BBC is to be read in accordance with section 368R(5) and (6).”.
(2) In the application of section 368(3)(b) to the Channel Islands and the Isle of Man, “on-demand programme service”, and references to the provision of such a service by the BBC, have the same meanings which they have in Part 3 of the Communications (Television Licensing) Regulations 2004 (as amended by regulation 5 of these Regulations).
You can watch any other catch-up TV Service (non-live content only), ALL4, ITV Hub, etc still without needing a TV licence. You need to avoid ALL Live TV and ALL (both live/catch-up) content from BBC iPlayer.
